Cast Iron Weights
Rugged Mass Standards for Industrial Calibration
When calibration moves from laboratory benches to factory floors, the standards must be strong, stable, and built to endure. Limra Instruments is a trusted manufacturer of Cast Iron Weights in India, supplying durable and precision-adjusted mass standards for industrial and commercial weighing systems.
Designed for heavy-duty applications, our cast iron weights deliver consistent performance under frequent handling and demanding environments.
Built for Strength & Long-Term Stability :
Industrial calibration requires weights that can withstand rough usage without compromising mass accuracy. Limra Cast Iron Weights are manufactured using:
- High-quality graded cast iron
- Precision casting techniques
- Stable density material selection
- Controlled finishing and adjustment
Each weight is engineered to maintain its nominal value within permissible tolerance limits.
Designed for Industrial Applications :
Our cast iron weights are widely used for:
- Platform scale calibration
- Weighbridge testing
- Floor scale verification
- Crane scale validation
- Industrial weighing inspection
- Trade and commercial verification
They are ideal for field calibration teams and maintenance departments.
Product Features :
- Heavy-duty cast iron construction
- Corrosion-resistant protective coating
- Clearly marked weight value

Frequently Asked Questions
What are cast iron weights and what are they used for?
Cast iron weights are large, heavy test weights used to calibrate platform scales, floor scales, truck scales, and other industrial weighing equipment in the 1 kg to 50 kg+ range. They're far more cost-effective than stainless steel at these higher denominations, making them the standard choice for Legal Metrology inspectors and scale service technicians across India.
What is the OIML accuracy class of Limra cast iron weights?
Typically OIML Class M1 or M2 the appropriate class for calibrating commercial and industrial scales. M1 is the higher accuracy class for Legal Metrology verification of trade scales; M2 serves as a secondary workshop reference. Cast iron isn't suited for precision or analytical balances those need stainless steel F or E class weights.
What denominations of cast iron weights does Limra supply?
We supply 1 kg, 2 kg, 5 kg, 10 kg, 20 kg, and 50 kg denominations, covering most commercial and industrial scale calibration needs. For very high-capacity scales like weighbridges, stacking multiple cast iron weights is common. Tell us your scale capacity and calibration points and we'll recommend the right combination.
Do cast iron weights from Limra come with calibration certificates?
Yes, traceable to national standards. This matters for Legal Metrology compliance when an inspector verifies your commercial scale, they check that the calibration weights used are themselves certified. For ISO 9001 or similar audits, documented traceability of all measurement standards is a standard requirement.
How do cast iron weights compare to stainless steel weights which should I choose?
It comes down to application and accuracy class. Cast iron is cost-effective for large denominations (1 kg+) at M1/M2 class ideal for platform and floor scales. Stainless steel costs more but is necessary for F1/F2 and E class precision work where surface quality and corrosion resistance matter, like lab or jewellery balance calibration. Most factories use cast iron for platform scales and stainless steel for precision balances.
